ZWPOWER13 posted:I have both the Silver and the Rare Black Version. I disassembled mine, cleaned all the gears and shafts. I used Red N Tacky 2 for grease and oiled everything up with Labelle 107 and both of mine run extremely smooth and fast, but when it comes to pulling, it can only pull 6 out of the 10 Pullmans Lionel Made for it :-)
This frame is from an 18045. In addition to what Mark suggests, check the crossheads for drag. I found the guides on mine were not parallel causing significant drag. Also the main rod was rubbing on the siderods.
I found an ammeter between the transformer and track to be a good diagnostic tool. If it jumps around or increases at the same point of every wheel revolution something is rubbing.
